Procedure: A mixture of 10.0 g (0.033 mole) of α,α-bis(4-fluorophenyl)-4-piperidine-methanol, 6.5 g (0.033 mole) of 3-chloro-N-methyl-N-phenylpropanamide, 14.0 g (0.132 mole) of anhydrous sodium carbonate and 0.3 g (0.002 mole) of potassium iodide in 100 ml of N,N-dimethylformamide was heated on a steam bath for 16 h. The mixture was poured into 2 L of water and extracted three times with 500 mL portions of ethyl acetate. The ethyl acetate fractions were combined, washed with water and brine, dried (MgSO4) and concentrated under reduced pressure to give a yellow glass. The glass was purified by column chromatography using 250 g of silica gel on a 65 cm×4 column, eluted with ethyl acetate. The fractions containing the desired product were combined and concentrated under reduced pressure to yield 11.0 g (72%) of a white solid. A portion of this solid was recrystallized from ethyl ether to give a white solid, mp 73°-75° C. was heated on a steam bath for 16 h extracted three times with 500 mL portions of ethyl acetate washed with water and brine dried (MgSO4) concentrated under reduced pressure to give a yellow glass The glass was purified by column chromatography eluted with ethyl acetate The fractions containing the desired product concentrated under reduced pressure

Procedure: A solution of 107.2 g (1.00 mole) of N-methylaniline in 150 ml of tetrahydrofuran was added dropwise to a solution of 90.4 g (0.71 mole) of 3-chloropropionyl chloride in 250 ml of tetrahydrofuran. The reaction temperature was maintained between 5° and 15° C. throughout the addition. After the final addition, the solution was filtered to remove a solid precipitate, and the filtrate was concentrated under reduced pressure to yield 130.0 g (91%) of a dark oil. An analytical sample was prepared by filtering the oil through a small bed of silica gel and eluting with ethyl acetate-hexane (1:5). The fractions containing the desired product were combined and concentrated under reduced pressure to give a light-yellow liquid. The liquid was partitioned between ethyl acetate and a saturated sodium bicarbonate solution. The ethyl acetate layer was washed with water and brine, dried (MgSO4), and concentrated under reduced pressure to give the title compound as a light-yellow oil. The reaction temperature was maintained between 5° and 15° C. throughout the addition After the final addition the solution was filtered to remove a solid precipitate the filtrate was concentrated under reduced pressure
